Bandpass Filters

Description

Bandpass filters are designed to transmit a specific range of wavelengths and block light on either side of that range. These filters are denoted by their center wavelength and bandwidth. The center wavelength (CWL) is the arithmetic mean of the wavelengths at 50% of peak transmission. The full width at half maximum (FWHM) is the bandwidth at 50% of peak transmission. 

Chroma Technology’s Single Bandpass Filters are precision-engineered for high-performance in fluorescence microscopy, Raman spectroscopy, imaging applications and many more. Ensure precision and efficiency in your scientific instrumentation with reliable optical filters.

Key Features:

• 214 – 2800 nm wavelength range
• 4 -100 nm FWHM
• The durable coatings are designed to withstand environmental challenges like humidity and temperature fluctuations. Most filters are sputtered with hard-coated thin films
• Available in standard and custom sizes for diverse application requirements.
• Unmounted or mounted in aluminum rings

Applications:

• Astronomy
• Colorimetry
• Machine Vision
• Raman
• SWIR
• And many more

There are more than 270 single band bandpass filters with central wavelengths ranging from 214 nm to 2310 nm and over 100 multi-band bandpass filters with up to 5 bands in the standard portfolio, and even more on request.
